Closeup insects from the Bois Brule River
Female Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Spinner
View 6 PicturesI'm not sure of the species of this female spinner, and unfortunately I never found the associated males or duns to aid in identification. The egg-laying flight and fall of fairly large clouds of these females caused good rises of choosy trout for a week or so around early July on a large, cold spring creek in the northwoods. There is a distinctive stripe down the female's back, identical to that on this specimen collected a month later. Cicadidae (Cicadas) Cicada Adult
View 4 PicturesI found this cicada and several like it in the grass near my car as I put my waders on. Some of them were singing in the trees above the river, too, but I did not see any fall into the water. Polydrusus (Green Weevils) Beetle Adult
View 3 PicturesThis is an iridescent green terrestrial (Terrestrial: Insects which live on land and are fed on by trout only when they incidentally fall into the water are known as "terrestrials" to fly anglers, and they're very important in late summer.) beetle. They're common in northern Wisconsin's forests during the middle of summer, and I found them on the water's surface more than any other terrestrial (Terrestrial: Insects which live on land and are fed on by trout only when they incidentally fall into the water are known as "terrestrials" to fly anglers, and they're very important in late summer.) insect. I saw the trout take a few and caught some trout on an imitation.
